WHAT ? His serve never held his game ...Davydenko served better in the second set. His focus should be to just get the serve in, to limit double faults. That's what he's done this season and why his seasonal first serve percentage is 70+ percent. Today he tried hitting big serves and missed and double faulted or hit horrible second serves.
The one positive that can be said is the serve isn't totally holding the rest of his game back anymore.
